Hand-guard for automatic firearms



Dec. 1932- R VON FROMMER HAND GUARD FOR AUTOMATIC FIREARMS Filed March23, 1932 Patented Dec. 27, 1932 @NETEE ETATEfi FATENT errata RUDOLF VONFROMMER, OF BUDAPEST, HUNGARY HAND-GUARD FOR AUTOMATIC FIREARM SApplication filed March 23, 1932, Serial No. 600,740, and. in HungaryMarch 24, 1931.

The invention relates to an improved handguard for automatic fire armsand more particularly to a further modification and perfect-ion of thehand-guard protected in the patent Serial No. 491,571/1930.

The above mentioned patent refers to a sliding cover and a hand-guard;the latter was a projection made integral with the gunstock orconstituting a separate part secured on the same and signed by 8 in thedrawing of said patent. This projection was arranged under the path ofthe sliding cover and had the destination to prevent that the hand ofthe shooter, when shooting may touch the fire arm above this projection.The breech of automatic fire arms at automatical operation slides with avery great speed backwards and consequently the handle of the breech isalso rapidly moved to and fro, and

this fact may be dangerous for the shooter.

In order to avoid this danger it was already proposed to apply a handlecapable of being disengaged, this however requires the application ofcomplicated mechanisms which are to be avoided in fire arms used in war.

When the hand of the shooter comes accidentally behind the handle movingspeedily backwards, this prevents not only the regular operation, thatis to say the return movement, but also the hand catching the fire armbehind said handle will be hurt. This was hindered by the projection 8described in the above mentioned patent, which project-ion served as alimit for the upwards movement of the left hand of the shooter.

At this arrangement it was still possible to pass the confineconstituted by this projection, as the passing could not be surelyprevented by the same.

The object of the present invention is to construct said projection insuch a manner, that this dangerous mode of catching the fire arm shouldbe rendered impossible. While the arrangement according to the abovementioned patent showed only a confine, the present construction makesthe wrong catching quite impossible. This is attained by a constructionof this projection, 50 which renders the catching of the latterpainfully disagreeable for the shooter. In order to accomplishthis'task, the smooth pr0jection of the above mentioned patent will beprovided with sharp edges or teeth, so that the seizing of the same willbe impossible. At this arrangement it is not necessary to call theshooters attention to the fact that he has to put his hand only belowthis projection, but not on or above the same as when touching the firearm on or above the projection according to the invention, he willwithdraw his hand immediately, because the edges and teeth prevent thecatching of the fire arm on this place, and much less is possible topress the fire arm against the shoulder of the shooter. In order toprevent every possible hurting of the hand pushing forward the breechwhen the automatic fire arm is operated manually, the teeth of saidprojectlon may have the form of forwardly directed saw-teeth; thus theforwardly moving hand is not hindered in its free movement.

In the accompanying drawing one form of realization of the invention isshown by way of example.

Fig. 1 is a side elevation of apart of the fire arm. 7

Fig. 2 is a top plan view of the same.

Fig. 3 is a section taken on line. III of Fig. 2.

After the explanation given above it is a further description of theinvention scarcely necessary. It is easy to conceive, that the catchingof a projection 2 provided-with sharp teeth 1 is impossible. Manuallyoperated fire arms must be, as it is known, caught firmly because of thekick, and this toothed projection cannot be even lightly caught, andmuch less firmly seized Without painful hurtingof the hand, so that aprojection of this kind obliges the'shooter to shun the same of the handdo not touch these teeth at all when opening said breech, but whenclosing the same the forward moving hand will touch the oblique side ofthe pyramidal teeth and 5 will glide on them without hurting itself.

I claim:

1. In an automatic fire arm, a hand-guard constituted by a protectingprojection of the gunstock arranged under the path of the 1 slidingcover, sharp teeth on said projection adapted to make disagreeable, thatis, painful the catching of said projection.

2. In an automatic fire arm, a hand-guard constituted by a protectingprojection of the gunstock arranged under the path of the sliding'cover, teeth with sharp points of said projection adapted to makedisagreeable, that is, painful the catching of the latter.

3. In an automatic fire arm, a-hand-guard constituted by a protectingprojection of the gunstock arranged under the path of the slidingcover,forwardly directed sharp saw teeth on said projection extending to thefront and adapted to make disagreeable, that is,.painful the catching ofsaid projection. r r I r 4. In an automatic fire arm, a hand-guardconstituted by a protecting projection of the gunstock arranged underthe path of the sliding cover, forwardly directed sharp saw teeth onsaid projection having the form of pointed pyramids and adapted to makedisagreeable,that is, painful the catching of said pro jection.

5. In an automatic fire arm, a hand-guard constituted by a separate partarranged on r V :3

the gunstock under the path of the sliding cover, sharp teeth on saidpart adapted to make disagreeable, that is, painful the catching of thelatter.

6. In an automatic fire arm, a hand-guard constituted by a separate partarranged on the gunstock under the path of the sliding cover, teeth withsharp points on said part adapted to make disagreeable, that is, paingful the catching of the latter. j 7 w 7. In an automatic fire arm, ahand-guard constituted by a separate part arranged on the gunstock underthe path of the sliding cover, forwardly directed sharp saw teeth ofsaid part adapted to make disagreeable, that is, painful the catching ofthe latter.

8. In an automatic fire arm, a hand-guard constituted by a separate partarranged on the gunstock under the path of the sliding cover, forwardlydirected sharp saw teeth of said part having the form of pointedpyramids and adapted to make disagreeable, that is, ainful the catchingof said part.
